Question

In some populations of spotted nettle, the plant's leaves are covered with short barbed hairs called trichomes. In other populations the leaves are smooth. You hypothesize that the trichomes are important in preventing herbivory by insects. Which of the following experiments and predictions is the best test of your hypothesis?

Transplant 60 plants from each type of population to the other population's habitat, and cover 30 of the plants that you move in each habitat with mesh cages that exclude insects; plants in cages will survive better than transplanted plants not in cages.

Transplant 60 plants from each type of population to the other population's habitat, and cover 30 of the plants that you move in each habitat with mesh cages that exclude insects; plants in cages will have lower herbivory than transplanted plants not in cages in the trichome population but not the smooth population.

Transplant 60 plants from each type of population to the other population's habitat, and cover 30 of the plants that you move in each habitat with mesh cages that exclude insects; transplants to the population with trichomes will have lower herbivory than plants moved to the population with smooth leaves.

Explanation / Answer

The answer is D. Transplant 60 plants from each type of population to the other population's habitat, and cover 30 of the plants that you move in each habitat with mesh cages that exclude insects; transplants to the population with trichomes will have lower herbivory than plants moved to the population with smooth leaves.

The transplants having trichomes will be better adapted to have lower herbivory than plants with smooth leaves.
